This song is about a girl waiting for her period to see if she's pregnant. She's in a bad relationship and is waiting to find out to tell her boyfriend, but by the end of the song, she decides that she'll leave him either way, since she doesn't want to be a victim of his bad behavior.

This is the highest-charting song on the Hot 100 with the word Wednesday in the title. The only other entry containing that day is "Wednesday" by the Royal Guardsmen, which hit #97 in 1967.
